Plastic Table Board Edge Structure to Prevent Clothing Hooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic table boards are prone to clothing getting hooked and damaged by the side edges, and the edges are sharp enough to scratch fingers due to their design.
Innovation Solution
A plastic table board with a reinforced frame and specific edge design, featuring a downward-extending side edge with a cambered connecting surface, a circular arc chamfer, and lug bosses to prevent clothing and fingers from being hooked, and to enhance stability and longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the top panel has downward-extending side edges to cover bonding traces, then the appearance is improved, but the side edges become sharp and hook clothing causing damage
Solution Approach 1:
The patent applies curvature by forming a rounded blocking end at the bottom of the side edge, replacing the sharp angular edge with a curved surface. This curvature prevents clothing from being hooked while maintaining the downward-extending side edge structure for aesthetic purposes. The rounded end creates a smooth transition that eliminates the harmful sharp edge.
Solution Approach 2:
The patent converts the potentially harmful sharp edge into a beneficial rounded blocking end. The same downward-extending side edge that originally caused clothing damage is transformed by adding a rounded terminus that actively prevents hooking. The structure that created the problem is modified to provide the solution.
2Shape
If the side edge is made sharp to prevent visibility of bonding traces, then the aesthetic quality is improved, but the edge becomes dangerous to fingers and clothing
Solution Approach 1:
The patent applies curvature by forming a rounded blocking end at the bottom of the side edge, replacing the sharp angular edge with a curved surface. This curvature prevents clothing from being hooked while maintaining the downward-extending side edge structure for aesthetic purposes. The rounded end creates a smooth transition that eliminates the harmful sharp edge.
3Object-affected harmful factors
If a reinforced frame is added to prevent edge hooking, then clothing damage is prevented, but the device complexity increases
Solution Approach 1:
The patent merges the protective function with the existing side edge structure by forming the rounded blocking end as an integral part of the side edge. Rather than adding a separate protective component, the protection is incorporated into the original structure, reducing overall complexity while achieving the protective function.
Solution Approach 2:
The patent applies local quality by modifying only the critical area (the bottom end of the side edge) where the hooking problem occurs. The rest of the side edge structure remains unchanged, maintaining its aesthetic function. This localized modification minimizes the impact on overall device complexity while solving the specific problem.
